Hello community.
I am interested in the Milltek Valvesonic exhaust system with center silencer.
Since I come from Germany and we have stricter emissions and volume laws, I would be interested in how much DB this system does when the flap is closed.

I am also interested in whether this system tends to boom with Stronic.

best regards

Pe
